Additive manufacturing is a layer-by-layer strategy enabling the advanced design and fabrication of complex 3D objects and structures, overcoming geometry limitations and reducing waste production compared to conventional technologies. Among various additive manufacturing technologies, digital light processing (DLP), is an additive manufacturing technology used to print photopolymer parts, using a projected light source to cure an entire layer at once. Initially developed for pure resins, recent advances have demonstrated the potential of DLP in the polymerization of ceramic and metal-loaded suspensions, enabling the fabrication of ceramic and metal components after proper debinding and sintering. Such flexibility increases the potential of DLP for different applications, ranging from dental implants and bone scaffolds to smart biomaterials for soft robotics, smart wearables, and microfluidic devices. The review provides an overview of DLP technology and its recent advances; specifically, the review covers the photopolymer properties, the ceramic and metallic feedstock preparation, and the light-matter interaction mechanism underpinning the printing and post-processing steps. Finally, a description of the current application is provided and complemented with future perspectives.

“…The density of the powder mixture is provided by the manufacturer, and further verification was made to calculate the density of the powder mixture by using the Archimedes principle after air quenching which was in good agreement with the supplier's data along with a standard deviation of around 0.1. The optimum amount of dispersant is 3 mg per square meter of ceramic powder (EB01) surface area [20]. The equation Eq.…”

“…In both processes, the light projects in form of a 2D image to cure the binder plane-by-plane. LCD technology has quickly gained popularity, since they offer a fast and cost-efficient alternative to other VPP systems [19,20]. Although the use of DLP in ceramics AM has been widely explored in most recent literature [16,[21][22][23][24][25], no study demonstrated the feasibility of printing a commercial ceramic core with more complex design features using mainstream commercial LCD screen-based printers.…”

“…Previous studies demonstrated that reducing the overall viscosity of ceramic inks and increasing the reactivity of the photocurable (meth) acrylate monomers (binder mixtures) enhances the mechanical property of the green bodies (printed part prior debinding and sintering) [19,20]. However, the print temperature, as one of the process parameters, can also play a significant role, because the viscosity of the ceramic suspension decreases with the increase of temperature and can be regarded as an alternative solution to modify the rheology of the mixtures during the printing process.…”

Electroconductive polymers are the materials of interest for the fabrication of electro-conductive tissues. Metal ions through the redox systems offer polymers with electrical conductivity. In this study, we processed a gelatin methacrylate (GelMA) network with gold nanoparticles (GNPs) through a redox system with parahydroxybenzaldehyde (PHB) or curcumin to enhance its electrical conductivity. Induction of the redox system with both PHB and curcumin into the GelMA, introduced some new functional groups into the polymeric network, as it has been confirmed by H-NMR and FTIR. These new bonds resulted in higher electro-conductivity when GNPs were added to the polymer. Higher electroactivity was achieved by PHB compared to the curcumin-induced redox system, and the addition of GNPs without redox system induction showed the lowest electroactivity. MTT was used to evaluate the biocompatibility of the resultant polymers, and the PHB-treated hydrogels showed higher proliferative effects on the cells. The findings of this study suggest that the introduction of a redox system by PHB in the GelMA network along with GNPs can contribute to the electrochemical properties of the material. This electroactivity can be advantageous for tissue engineering of electro-conductive tissues like cardiac and nervous tissues. Graphical Abstract
